Dive teams finally found two guys that went ice fishing 22nd of January on Lake Sakakawea in North Dakota, Car went through in 60 feet of water. Found car nose down with door open and they we found outside car near by, ice was only 2 inches thick, they suspect coalbed methane gas was the cause of the thin ice, surrounding ice is upwards of 2 ft close to 3 ft where we have been fishing. Area is very close to abundant source of coal that is mined near by. My feelings go out to their friends and relatives.
